HANOVER — The roadway on Route 10 West has been cleared of spilled salt and sand as of 7 a.m., the state Department of Transportation reports on 511nj.org.

Hanover Patrol Officer Ryan Williams said the accident occurred at 3:39 a.m. when a snow plow truck owned by All County Paving overturned on Route 10 West near School Street after the lip of the plow caught the concrete median.

All westbound lanes on Route 10 were subsequently closed and detoured due to spilled salt and sand in the roadway, DOT said.

The driver of the vehicle was taken to Morristown Medical Center for evaluation, but no injuries were reported, Williams said.

Clean up efforts lasted about three and a half hours as bulldozers were mobilized to clear sand and salt from the roadway, DOT said. Road crews also pumped fuel out of the vehicle's gas tank prior to towing it away, Williams said.

No other vehicles were involved in the accident.

One eastbound lane was also closed as of 5:33 a.m., but was clear by 6 a.m., DOT said.
